Implantable collamer lenses (ICL) have gained popularity for correction of myopia where kerato-refractive procedures are not indicated as in cases of high myopic refractive errors. Toxic anterior segment syndrome (TASS) is a very uncommonly reported postoperative complication following ICL implantation. A young patient developed severe corneal oedema and anterior segment inflammation on the first day after ICL implantation. Read More

University of Washington Department of Ophthalmology, Seattle, Washington, USA.

Purpose: We report a case of a highly myopic pseudophakic patient who received off-label placement of a phakic intraocular lens (pIOL) via a "piggyback" technique, allowing the placement of an intraocular lens (IOL) in his fellow eye, resulting in improved visual acuity and emmetropia.

Case Report: A 66-year-old, highly myopic, pseudophakic male with an IOL implant in his left eye was referred for second opinion for surgical options for his phakic right eye. Given the severe myopic status of both eyes, he received off-label placement of a posterior chamber pIOL with a piggyback technique for the pseudophakic left eye followed by standard cataract surgery and intraocular lens implantation in the right eye.

The region of far peripheral vision, beyond 60 degrees of visual angle, is important to the evaluation of peripheral dark shadows (negative dysphotopsia) seen by some intraocular lens (IOL) patients. Theoretical calculations show that the limited diameter of an IOL affects ray paths at large angles, leading to a dimming of the main image for small pupils, and to peripheral illumination by light bypassing the IOL for larger pupils. These effects are rarely bothersome, and cataract surgery is highly successful, but there is a need to improve the characterization of far peripheral vision, for both pseudophakic and phakic eyes.

Implanting phakic IOLs (PIOLs) in phakic eyes is regarded as an established option in refractive surgery for many years when treating high myopia, hyperopia or ametropia. Even for eyes which show a combination of refractive errors (including astigmatism) this can be an appropriate option. The surgery itself requires certain anatomical and refractive requirements, since, as with any intraocular procedure, there are different possibilities of complication depending on the chosen IOL.

Purpose: To conduct a material analysis of spontaneously subluxated iris-fixated phakic intraocular lenses (IOLs) using light and scanning electron microscopy.

Background: Myopia is a condition in which the focusing power (refraction) of the eye is greater than that required for clear distance vision. There are two main types of surgical correction for moderate to high myopia; excimer laser and phakic intraocular lenses (IOLs). Excimer laser refractive surgery for myopia works by removing corneal stroma to lessen the refractive power of the cornea and to bring the image of a viewed object into focus onto the retina rather than in front of it.

Introduction: Currently, the use of multifocal IOL's remains controversial for patients with high myopia, especially because of the risk of retinal complications and poor quality of vision. Our goal was to evaluate this retinal risk and clarify the benefits obtained in this population in terms of visual acuity.

Patients And Methods: Twenty-nine highly myopic patients (52 eyes with over 6 diopters of myopia) aged 40-69 years with early cataract by LOCSIII were selected for multifocal lens implantation, based on a healthy endothelium and retina as well as better visual acuity corrected to at least 0.

Purpose: When comparing follow-up endothelial cell (EC) density measurements it is only possible to demonstrate cell loss in large cohorts or in pronounced cases due to the standard deviation of measurements. However, especially in clinical studies or refractive surgery patients, EC stability is an important factor. Thus we developed a computer program to achieve cell-by-cell alignment of conventional specular non-contact EC photographs. Read More

Refractive surgery includes all procedures which are primarily targeted at changing the refractive power of the eye. Currently laser-assisted in situ keratomileusis (LASIK) is indicated to correct myopia of up to - 8 D, hyperopia up to + 3 D and astigmatism up to 5 D. Photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK) are primarily recommended for myopia up to - 6 D and for greater refractive errors, phakic intraocular lenses (IOL) are the first choice (myopia greater than - 6 D and hyperopia greater than + 3 D).
